Specification of Letters Patent.

Patented Mar. 26, 1912.

Application filed April 8, 1911. Serial No. 619,806.

To all whom it may concern:

Be it known that I, MORRIS G. GI 1A LL- BURG, a citizen of the United States, resldmg at Lincoln, in the county of Lancaster and State of Nebraska, have invented new and useful Improvements in Railroad-Ties, of which the following is a specification.

This invention relates to railroad. ties and more particularly to metallicties.

Heretofore, in the use of metallic ties, no provision has been made for constantly takin care of expansion and contraction of the rails and of the varying widths of the wheels on the rolling stock. Therefore the bolts which held the rail clips to the tie were frequently sheared off or loosened to such an extent that derailment could not be prevented, frequent accidents happening in this manner.

It is the object of this invention to provide means for mounting one of the rails upon the movable support forming a part of the tie so that it may have relative movement toward and away from the other rail, as required by expansion'and contraction or by the differing treads of the different engines or cars passing over the track.

A further object of the invention is the provision of a metallic tie having means for mounting the rails in such a manner that one of them will be movable toward and away from the other rail and means for holding the movable rail to standard gage and for permitting its relative movement.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawings, which form a part of this application, and in which Figure 1 is a top plan view showing the preferable arrangement of spacing the adjusting ties. Fig. 2 is a top plan view of one of the adjusting ties on an enlarged scale.

Fig. 3 is a detail side elevation of the tie.

Fig. 4 is a longitudinal vertical section. Fig. 5 is a longitudinal horizontal section.

Referring more particularly to the drawings, l and 2 represent the separate rails of the track which are mounted, in the ordinary form, upon ties 3. At suitable intervals adjusting ties, or what may be termed gage ties, 4: are used. These gage ties l are each formed of rectangular metallic tubing either pressed into form from sheet metal or cast as an entirety, as is found desirable. The rail 2 is mounted directly upon the tie and is secured thereto by the clips 5 and 6, the latter being provided with slots 7 to receive the fastening bolts 8, so that the clip may be adjusted to accommodate varying widths or thicknessesin the bases of the rails.

Adjacent the opposite end of the tie the top thereof is cut away to form an aperture 9 and. slidably mounted within the tie is a rectangular tubular casing 10 upon which the rail 1 is mounted. This casing has journaled across its body a pair of shafts 11 and 12 which carry rollers 13 extending through slots 14 in the bottom of the casing and resting upon the bottom of the tie 4 so that the casing will ride easily thereover. The rail 1 is secured to the casing 10 by clips 15 and 16, both of which have raised terminal ends 17 forming shoulders 18 which limit the movement of the casing in both directions. The casing is further limited by means of a shaft 19 which extends across the body of the tie and is adapted to be engaged by the inner end of the casing. The shoulders 8 engage the walls of the aperture or opening 9.

In order to hold the rail 1 to gage and the casing 10 against the shaft 19, there is mounted within the tie, and resting against the outer end of the casing 10, an abutting plate 20 having a plurality of guiding tubes 21, one of which is arranged at each corner of the plate and adapted to receive similar but smaller tubes 22 carried at the corners of the spring plate 23. This spring plate carries a circular collar in its center, around which is secured a spiral spring 24. whose free or opposite end is adapted to engage and abut against the plate 20. The spring plate 23 is held in position within the end of the tie by means of a cap plate 25 having laterally extending ears 26 with bolt apertures therein to correspond with similar apertures in laterally extending ears 27 on the tie, suitable bolts 28 being used to connect the ears together and hold the cap plate in proper position. The lateral flange 29 carried by the cap plate extends up upon the sides of the tie and a similar base flange 30, secured to the bottom of the top plate, extends beneath the tie. These flanges prevent the ingress of dirt or other foreign material to interfere with the working of the casing 10. It will be noticed that the rail 1 cannot spread away from the rail 2 sufiiciently far to permit disengagement of the wheels of the train therefrom because the shoulder 18 on the clip 16 being positioned to engage the wall of the opening 9 only permits the movement of the rail 1 away from the rail 2 of about a maximum distance of one-half an inch.

These ties may be arranged closely together in the manner of ordinary Wooden ties, but are preferably arranged in the man ner shown in Fig. 1, wherein the ordinary wooden ties support the rail and the adjust- 'ing ties 4 are arranged at the joints between the rail, that is, one end of the ties is positioned beneath the joint of one rail and the opposite end is positioned beneath the opposite rail.

Having thus described the invention, what I claim as new is 1. In a device of the class described, a hollow body having an opening therein, a rail support slidably mounted in said body and exposed through the opening, means carried by the support for securing a rail thereon, said means adapted to engage the body to limit the movement of the support in one di rection, and an obstruction extended across the body of the tie to limit the movement of the support in the opposite direction.

2. A tie comprising a hollow body, arail support slidably mounted therein, a rail mounted on said support, a second rail secured upon the tie, and means normally acting to hold the first rail to gage with the second rail.

3. A tie comprising a hollow body, a rail support slidably mounted within the body at one end and exposed to receive a rail, a rail mounted thereon, a rail secured upon the opposite end of the tie body, and a spring to normally hold the first rail to gage with the second rail.

4. A tie comprising a hollow body, a rail support slidably mounted within the body at one end and exposed to receive a rail, a rail mounted thereon, a rail secured upon the opposite end of the tie body, a spring 'to normally hold the first rail to gage with the second rail, and means to limit the movement of the support against the tension of the spring.

5. A tie comprising a hollow body, a rail support slidably mounted within the body at one end and exposed to receive a rail, a rail mounted thereon, a rail secured upon the opposite end of the tie body, a spring to normally hold the first rail to gage with the second rail, means to limit the movement of the support against the tension of the spring, means to limit the movement of the support in the opposite direction, and removable means for supporting the spring in position to act upon the support.

In testimony whereof I affix my signature in presence of two witnesses.
